Convert incoming numbers to E.164 prior to range matching.

TelephonyManager#requestNumberVerification performs range checking on the
original unformatted phone number from the network.  In some regions like
the UK, the country prefix may not be present and a leading `0` may be
present in the phone number.

To ensure that these numbers are properly handled, we will now use
PhoneNumberUtils to convert the incoming number from the network into
`E.164` format prior to passing for match checking.  Since a 0 prefixed
number received from a UK carrier is formatted correctly with the `+44`
country code, this ensures that these numbers are handled correctly
by the matching API.

Test: Added new unit tests to cover matching of these numbers.
Test: Manual testing using shell command to confirm correct behavior of
the API from an end-to-end standpoint.
Test: Via test app and shell override.
